An audible hum or hum bars is often generated when A/V components are connected to a cable TV or satellite system directly. Eliminate this annoying interference with the Ground Breaker, a feed-through surge protector that resides on your cable line. The coax cable is sold separately.

NOTE: Not compatible with HD signals.

The Ground Breaker isolates ground potential differences within an audio/video system without affecting the RF signal, so you'll be left with nothing but clear audio and visual communication.

Works fine 'cept for HD transmissions which is kinda a problem. Had to upgrade to $50 groundbraker. No problems with shipping.

I have a television, amateur radio, police scanner and FM broadcast radio connected to an audio mixer. I was experiencing a strong hum in the audio output. After researching this on the internet I discovered the hum could be coming from my cable TV feedline. Sure enough if I disconnected the coax cable going into the cable tv box the hum disappeared. I ordered this ground breaker and installed it on the back of the cable box and the hum is completely gone. There is no degredation in the cable tv audio or video. This device works great if you have audio hum caused by a ground imbalance on your incoming cable TV feedline.

Excellent Ground Breaker!! The TV cable was making my Bravia Sony to cut on and off by itself. Comcast solution was to run it thru my VCR tuner. The ground breaker solved the problem in seconds that I been wrestling for months. Thanks so much for a great solution that cost nothing compared to my $3,000 TV.

This solved the horrible feedback/grounding problem we were having with our subwoofer. Too bad we tried soo many other things first. This works great.

Great result, stopped the hum and the price was very good, I'd looked at one made by Jensen and that was 4 times the price!!
